SIRIUS 3RT contactors for extended operating conditions
Siemens SIRIUS 3RT contactors for extended operating conditions
Traction contactors and versions for extended ambient conditions to IEC 60077.
These versions are designed for the vibration, shock loads and wide voltage tolerances found in rail vehicles and on ships. The coil operates over an extended range of 0.7 to 1.25 Uc, and the electronic operating mechanism keeps pick-up conditions stable even with a fluctuating on-board supply.
Parent category: Siemens SIRIUS 3RT contactors.
Product benefits
- Proven SIRIUS 3RT range from Siemens – available worldwide and maintained over decades
- Consistent modular system: auxiliary switches, surge suppressors and link modules fit across sizes
- Screw or spring-loaded terminals – spring-loaded saves assembly time and is vibration-proof
- Versions with electronic operating mechanism reduce holding power and work over a wide voltage range
- Approvals to IEC and UL/CSA, so the same plant can be operated in Europe and North America
